土石混合体由粗料和细料两部分组成,目前作为路基填筑材料被广泛使用在国内外的公路建设上,其力学性能一直受到广大研究者的关注,土石混合料的抗剪强度组成以及剪切变形机理,是关注的重点。该文采用大型三轴试验的手段研究土石混合料的强度特性,着重考虑含石量、密度和围压这一系列因素对土石混合体强度特征的影响,通过改变这些指标研究土石混合体抗剪强度的衰变规律。
The mixture of soil and stone consists of two parts, coarse material and fine material. Nowadays, as the roadbed filling material, it is widely used in highway construction both at home and abroad. Its mechanical property has been paid attention by researchers, the shear strength of soil-stone mixture, Shear deformation mechanism is the focus of attention. In this paper, we use large-scale triaxial test to study the strength characteristics of soil-rock mixture. The effects of the factors such as rock content, density and confining pressure on the strength characteristics of soil-rock mixture are studied. By changing these indexes, Intensity decay law.
